Backup size increased???

I'm sorry if this ain't the right section to post this, but I'm not really sure where's the best place to post about such a weird issue like this one.

I'd managed my backups with WBSF Manager 3.0.1 alright, but because that demanded me to keep my backups in 4.3GB isos (and I was running out of HDD space), I decided to start using Wii Backup Manager 0.3.8 Build 61 instead, and keep all my games as wbsf (certainly less than 4.3GB each).

But something happened. At first I thought it was my mind playing games on me, but I'm completely sure now that my stored backups have increased in size.

I have for example, Tetris Party Deluxe, which I just made sure by making the backup again was 56MB in size, and now for some reason, the one I kept stored is 246. Just what happened there?

And not just that one! 350MB New Super Mario Bros. Wii is now 538. I can't tell YET if it's happened with any others, but I find this likely...

On the other hand, Pikmin 1, Mario Power Tennis and Star Wars The Force Unleashed 1 just downright stopped being recognized by Wii Backup Manager (the log says Source: WBSFPartition.OpenFromHandle, Invalid partition header, Not a WBSF partition) even though it worked alright before, for a long time. And the weirdest part is that I certainly did not touch those games in all this time. I noticed only because they kept getting recognized and showing up on my list every time I chose to Add a Folder to the thing, but that's it.

Anyways, I think this is all I can say to explain the situation, but, well if you need anything else I'll do my best. I already tried converting them back to Iso, but the size keeps the same increased number. If anyone can tell me what am I doing that's causing this, then please do so I can stop it! This is just too weird and I don't like it. Thanks in advance! And even if you can't help, thanks anyways just for reading. I'll look forward to all you have to say about this.

Yup, you hit gold. I select what you say and all game show their original size. This surprises me because it really looked like they had GAINED a partition somewhere along the way, but I guess I was fooled. Thanks a lot, that solves the mystery.

Anyways, should I really select this? What's in this roughly 150~200MB not game partition that I'd be discarding by doing so?

Btw, no clue on why some wbfs would show that error I mentioned even though all I'd do with them was load them into Wiibackupmanager? I don't think it was a hardware error, and chkdsk ran just fine. Could it had been the program's fault or should I look around for other culprits?
